Quantitative trait loci Study guides, Class notes & Summaries

what is a qualitative trait in terms of this class? correct answer: the quality of having a trait or the absence of it what is a quantitative trait in terms of this class? correct answer: can be measured on a numerical scale, such as symptom count or height _______________ traits fit well with a case-control designation correct answer: qualitative if a marker and trait loci are linked, the allele frequencies will.... correct answer: differ between cases and controls if a marker a...

Biology 1108 Exam 3 1. An important result from the monohybrid cross experiments was that phenotypes appeared in predictable ratios, indicating that only one copy of each gene passes from a parent to its offspring. This is now referred to as: a. Sympatric speciation b. The Hardy-Weinberg Equilibrium c. The Law of Independent Assortment d. The Law of Segregation e. The Theory of Natural Selection 2. In Mendel's crosses, he found that it was possible to recover traits that were present i...

Evolutionary Analysis Ch.9 questions fully solved graded A+ 2023 best-fit line - correct answer The line that most accurately represents the trend of the data in a scatterplot; typically best-fit lines are calculated by least-squares linear regression. likelihood ratio - correct answer Spontaneous movement of a substance from a region of high concentration to one of low concentration (i.e., down a concentration gradient). independence (statistical) - correct answer Lack of association amo...

Simply Inherited Traits Correct Answer: - Traits affected by: coat color, horns - Qualitative or categorical; rarely quantitative Polygenic Traits Correct Answer: - Affected by many genes with no gene having an overriding influence - Growth rate, milk production, ribeye area - Typically qualitative or continuous in expression - Greatly influences by environment - Lack of feed, heat/cold stress, training of quarter horses Threshold Traits Correct Answer: - Some polygenic have catego...

what does it mean to be genetically polymorphic? to have different forms of individuals as a result of discontinuous genetic variation ex: when more than one allele occupies that gene's locus within a population (hair color) What kind of traits did Mendel observe? simple, distinctive phenotypic traits that are determined by single genes (monogenic and qualitative) Quantitative traits are ________________ polygenic what does it mean for a trait to be polygenic? The expression of the trai...

A Galton Plot is the old name for parent-offspring regression. Why was Galton's work so significant? - Because it was the first effort to estimate the degree to which a quantitative trait has a genetic basis A neutral marker is one which is not undergoing any...? - Selection A review of selection gradients estimated in natural populations found that...? - Selection gradients are typically weak to moderate, usually well below 0.5 A substitution of adenine for guanine could results in wh...
